摘要： Testing apparatus is provided in the form of a pen and has a body (11) and cap (12). The body (11) has an inlet (13) at its tip which communicates with a fuel cell chamber (14), containing a fuel cell (15), and, via that chamber, with a passage (16) and a cylinder (17). A piston (18) is mounted in the cylinder (17) for operation by a button (19), a spring (21) and latch (22) such that it can draw air through the inlet (13) to the fuel cell (15). If the inlet (13) is placed in a user's mouth the apparatus can provide an indication of his breath alcohol concentration, for example, on display (23).

摘要： An alcohol concentration sensor provided a tube shaped means (21) of which the top end (211) is closed with a top end closing means (20) and of which the bottom end (212) is remained open, a gas supply tube means (22) which penetrates the top end closing means (20) to extend down into the tube shaped means (21), which is provided an air blower means (24), and of which the lower end (221) termi­nates slightly upper than the bottom end (212) of the tube shaped means (21), thereby the lower end (221) of the gas supply tube means (22) is soaked into a liquid (10) con­taining water and alcohol, of which the alcohol concentra­tion is required to be determined, deeply sufficient to allow the air bubbles flown out of the gas supply tube means (22) into the liquid (10) to absorb sufficient quan­tity of alcohol contained in the liquid (10), whenever the tube shaped means (21) is soaked in the liquid (10), a gas drawing out means (26) which penetrates the top end closing means (20), a gas temperature sensing means (27) which is connected with the gas drawing out means (26) for deter­mining the temperature of the gas in the neighborhood of a gas oxidization means for oxidizing the alcohol evaporated from the liquid (10), a temperature/alcohol concentration calibration means for calibrating the temperature of the gas toward the corresponding alcohol concentration, and an alcohol concentration output means for outputting the alcohol concentration determined by the temperature/alcohol concentration calibration means.

摘要： Ein Prüfröhrchen zum Nachweis von Gaskomponenten in Luft mit einem sich entlang der Längsachse des Prüfröhrchens ändernden Füllkörper soll derart verbessert werden, daß bei sich nicht veränderndem Strömungswiderstand eine entlang des Prüfröhrchens sich verändernde Empfindlichkeit für den nachzuweisenden Schadstoff erhalten wird. Dazu ist vorgesehen, daß der Füllkörper aus einer Zusammensetzung mit entlang der Längsachse sich ändernden Anteilen an aufgebrachtem Indikator und Trägersubstanz besteht.
